I can't tell if you used an odd lens or not. It could be the top tube & seatpin, it could be a 20 degree lens, it could be both. I don't like it, it gives me a headache. I'm off to look at a brick for a bit and re-gather a sense of perspective.

Dues,
The chainring bolts are Mibbleburn (approx 10-11 years old as are the arm and spider).

Convert,
The gear cables are Aligator from Clee Cycles. £19.99 a set. I had to but 2 sets for this bike cause the cables fun full lenth and the Aligator set would only do a full bike with the split cable routing.
They are really smooth though!

Nice suggestion Houns!!!! but i am not a fan of external BBs. I have not yet heard of one lasting more than 12 months or so.
Both of mine run Royce sq. tapers and with the chain off the cranks will spin 20+ full revs with a firm tap.
